aking treatment or passing
water.

Do not handle dogs or cats, especially strange or sickly ones.

Do not clean the ears with sticks or straws,--have a doctor do it for
you.

Do not have cheap, advertising dentists fix your teeth. Have the army
dentist fix them and see him at least once every six months,--or see a
good civilian dentist.

Do not have pictures tattooed on your skin.

Do not smoke other men's pipes.

Do not handle or touch wounds with anything but a first aid package.

Beware of chipped drinking glasses in cafes, restaurants and other
places. The slightest cut from such a glass whoso clipped part has
been in contact with the mouth of a syphilitic person will give you
syphilis.

Seek good companions like your mother and sister. Keep away from John
Barleycorn. He always wants to turn you over to a harlot.

Whores and prostitutes are all diseased and will give you germs that
will live to give diseases to you, your wife and your children, forty
years from now. Keep away from them.

Diseases Caught from Biting Insects

=1468. The more common diseases.= The following are some of the more
common diseases caught from the bites of certain insects: Malaria,
yellow fever, and dengue fever.

The germs of malaria, yellow fever and dengue fever live in the blood,
and are sucked up into the blood by mosquitoes when they bite.

Malaria germs, however, will develop only in the mosquito called,
_Anopheles_.

Yellow fever germs will develop only in the mosquito called,
_Stegomyia_.

Dengue fever germs will develop in the mosquito called _Culex_ and in
_Anopheles_.

After a period of development in these mosquitoes the germs will find
their way to the spit glands, and are injected into the person whom
the mosquito bites. (Note. Male mosquitoes cannot bite.)

_Absolutely the only way that malaria, yellow and dengue fevers can
possibly be caught is from mosquitoes._

=1469. How to avoid malaria, yellow and dengue fevers.= To avoid these
diseases, which are carried by mosquitoes, we screen all houses with
fine wire screens and use mosquito nets on the beds. Also, under
certain conditions we take daily doses of quinine in malarious
regions.

We kill the mosquitoes.

To do this we must know their habits.

Mosquitoes all lay eggs in water. These hatch
